<![CDATA[SOLVED - No local access to devices with new netmask]]>I changed the netmask for my LAN interface from /24 to /22
I have set the DHCP pool to 10.0.2.x
I have static clients in 10.0.1.x
I have servers and equipment statically assigned in 10.0.0.x

If i attempt to access a server in the 10.0.0.x range from the .1.x or .2.x I have very intermittent access. Some devices work fine, just like normal. Other devices work on and off and some aren't accessible at all. If i attempt to access from their web address it works fine so the servers are running however I can not get LAN side working. Any one have any advice on how to troubleshoot this?

If I set myself a static IP in the 10.0.0.x range I can access all the servers fine.

Would routers configured in AP mode interfere with this at all? That's all I can think of right now that might be causing this

Or maybe you have some devices that aren't DHCP from static mappings and are statically configured.

For the DHCP clients, you did everything that needs to be done. There's nothing more to it than making sure they've renewed their leases so they have the new mask.

I checked the devices and they are correctly getting the right netmask via the static DHCP.

Some are accessible no problem (Pi's) others such as QNAP NAS's or proxmox server are completely inaccessible. VM's on the proxmox servers are intermittently accessible.

This is bizarre.
IS there any different / better way to set this up?

Oh and when connecting via the VPN on 10.0.5 everything is accessible fine

It sounded like they were static IP, not static DHCP mappings.

Anything with a static IP configured has to be changed on that device, but not anything getting a static mapping via DHCP.

This is how it looks in the DHCP setting page

If I edit a static mapping there is no option for a mask?

I have restarted the DHCP server several times as well as the pfsense box itself, is this enough to renew the leases?

I forgot to add, all devices can access the internet fine

And renew the DHCP lease for all the dynamic ones.
